SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

12 Months Ended

Jan. 31, 2012

Significant Accounting Policies [Text Block]


1.	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

	Principles of Consolidation – The accompanying financial statements consolidate the operating results and financial position of Rex American Resources Corporation and its wholly-owned and majority owned subsidiaries (the “Company” or “REX”). All intercompany balances and transactions have been eliminated. As of January 31, 2012, the Company maintains ownership interests in five ethanol entities and manages a portfolio of real estate located in 12 states. The Company operates in two reportable segments, alternative energy and real estate. The Company completed the exit of its retail business during fiscal year 2009 although it will continue to recognize, in discontinued operations, revenue and expense associated with administering extended service policies.

	Fiscal Year – All references in these consolidated financial statements to a particular fiscal year are to the Company’s fiscal year ended January 31. For example, “fiscal year 2011” means the period February 1, 2011 to January 31, 2012. The Company refers to its fiscal year by reference to the year immediately preceding the January 31 fiscal year end date.

	Use of Estimates – The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

	Cash Equivalents – Cash equivalents are principally short-term investments with original maturities of less than three months. The carrying amount of cash equivalents approximates fair value.

	Concentrations of Risk – The Company maintains cash and cash equivalents in accounts with financial institutions which, at times, exceed federally insured limits. The Company has not experienced any losses in such accounts. The Company does not believe there is significant credit risk on its cash and cash equivalents. During fiscal years 2011(three customers), 2010 and 2009 (two customers), accounted for approximately 78%, 45% and 64%, respectively, of the Company’s net sales and revenue. At January 31, 2012 and 2011, these customers represented approximately 58% and 68%, respectively, of the Company’s accounts receivable balance. These customers (in fiscal year 2011) were Archer Daniels Midland, Biourja Trading, LLC and United Bio Energy.

	Inventory – Inventories are carried at the lower of cost or market on a first-in, first-out basis. Inventory includes direct production costs and certain overhead costs such as depreciation, property taxes and utilities related to producing ethanol and related by products. Inventory is permanently written down for instances when cost exceeds estimated net realizable value; such write-downs are based primarily upon commodity prices as the market value of inventory is often dependent upon changes in commodity prices. The write down of inventory was $153,000 and $0 at January 31, 2012 and 2011, respectively. Fluctuations in the write down of inventory generally relate to the levels and composition of such inventory at a given point in time.

	The components of inventory at January 31, 2012, and January 31, 2011 are as follows (amounts in thousands):


	2012		2011


Ethanol and other finished goods, net	$	5,318	$	2,347
Work in process		3,819		1,705
Grain and other raw materials, net		21,212		3,767


Total	$	30,349	$	7,819


	Property and Equipment –Property and equipment is recorded at cost. Depreciation is computed using the straight-line method. Estimated useful lives are 15 to 40 years for buildings and improvements, and 3 to 20 years for fixtures and equipment. The components of property and equipment at January 31, 2012 and 2011 are as follows (amounts in thousands):


	2012			2011


Land and improvements	$	25,094		$	21,899
Buildings and improvements		40,710			44,297
Machinery, equipment and fixtures		212,797			124,439
Leasehold improvements		366			440
Construction in progress		7,194			4,578


		286,161			195,653
Less: accumulated depreciation		(46,077	)		(25,842	)


	$	240,084		$	169,811


	In accordance with ASC 360-05 “Impairment or Disposal of Long-Lived Assets”, the carrying value of long-lived assets is assessed for recoverability by management when changes in circumstances indicate that the carrying amount may not be recoverable, based on an analysis of undiscounted future expected cash flows from the use and ultimate disposition of the asset. The Company recorded an impairment charge of $1,227,000 in fiscal year 2011, all of which is included in selling, general and administrative expenses. The Company recorded an impairment charge of $1,021,000 in fiscal year 2010, of which $165,000 is included in selling, general and administrative expenses and $856,000 is classified as discontinued operations in the consolidated statements of operations. The Company recorded an impairment charge of $1,533,000 in fiscal year 2009, of which $663,000 is included in selling, general and administrative expenses and $870,000 is classified as discontinued operations in the consolidated statements of operations. The impairment charges classified as selling, general and administrative expenses in fiscal years 2011, 2010 and 2009 relate to individual properties in the Company’s real estate segment. The impairment charges in fiscal years 2011, 2010 and 2009 classified as discontinued operations relate to individual stores in the Company’s former retail segment or individual properties that have been sold that were previously included in the Company’s real estate segment. These impairment charges are primarily related to unfavorable changes in real estate conditions in local markets. Impairment charges result from the Company’s management performing cash flow analysis and represent management’s estimate of the excess of net book value over fair value. Fair value is estimated using expected future cash flows on a discounted basis or appraisals of specific properties as appropriate. Long-lived assets are tested for recoverability whenever events or changes in circumstances indicate that its carrying amount may not be recoverable. Generally, declining cash flows from an ethanol plant or deterioration in local real estate market conditions are indicators of possible impairment.

	Depreciation expense was approximately $11,580,000, $15,660,000 and $10,462 000 in fiscal years 2011, 2010 and 2009, respectively.

	Investments and Deposits – Restricted investments, which are principally money market mutual funds and cash deposits, are stated at cost plus accrued interest, which approximates market. Restricted investments at January 31, 2012 and 2011 are required by two states to cover possible future claims under extended service policies over the remaining live of the service policy contract. In accordance with ASC 320, “Investments-Debt and Equity Securities” the Company has classified these investments as held-to-maturity. The investments had maturity dates of less than one year at January 31, 2012 and 2011. The Company has the intent and ability to hold these securities to maturity.

	The method of accounting applied to long-term investments, whether consolidated, equity or cost, involves an evaluation of the significant terms of each investment that explicitly grant or suggest evidence of control or influence over the operations of the investee and also includes the identification of any variable interests in which the Company is the primary beneficiary. The Company consolidates the results of one majority owned subsidiary, One Earth, with a one month lag as One Earth has a fiscal year end of December 31. The Company also consolidates the results of one majority owned subsidiary, NuGen, which has the same fiscal year as the parent, and therefore, there is no lag in reporting the results of NuGen. The Company accounts for investments in limited liability companies in which it may have a less than 20% ownership interest, using the equity method of accounting when the factors discussed in ASC 323 “Investments-Equity Method and Joint Ventures” are met. The excess of the carrying value over the underlying equity in the net assets of equity method investees is allocated to specific assets and liabilities. Any unallocated excess is treated as goodwill and is recorded as a component of the carrying value of the equity method investee. Investments in businesses that the Company does not control but for which it has the ability to exercise significant influence over operating and financial matters are accounted for using the equity method. Investments in which the Company does not have the ability to exercise significant influence over operating and financial matters are accounted for using the cost method.

	The Company periodically evaluates its investments for impairment due to declines in market value considered to be other than temporary. Such impairment evaluations include, in addition to persistent, declining market prices, general economic and company-specific evaluations. If the Company determines that a decline in market value is other than temporary, then a charge to earnings is recorded in the Consolidated Statements of Operations and a new cost basis in the investment is established.

	Revenue Recognition – The Company recognizes sales from the production of ethanol and distillers grains when title transfers to customers, upon shipment from the ethanol plant. Shipping and handling charges to ethanol and distillers grains customers are included in net sales and revenue.

	The Company includes income from its real estate leasing activities in net sales and revenue. The Company accounts for these leases as operating leases. Accordingly, minimum rental revenue is recognized on a straight-line basis over the term of the lease.

	The Company sold, prior to its exit of the retail business, extended service policies covering periods beyond the normal manufacturers’ warranty periods, usually with terms of coverage (including manufacturers’ warranty periods) of between 12 to 60 months. Contract revenues and sales commissions are deferred and amortized on a straight-line basis over the life of the contracts after the expiration of applicable manufacturers’ warranty periods. The Company retains the obligation to perform warranty service and such costs are charged to operations as incurred. All related revenue and expense is classified as discontinued operations.

	The Company recognized income from synthetic fuel partnership sales as production was completed and collectability of receipts was reasonably assured. The Company was paid for actual tax credits earned as the synthetic fuel was produced with the exception of production at the Pine Mountain (Gillette) facility. See Note 5 for a further discussion of synthetic fuel partnership sales.

	Costs of Sales – Alternative energy cost of sales includes depreciation, costs of raw materials, inbound freight charges, purchasing and receiving costs, inspection costs, shipping costs, other distribution expenses, warehousing costs, plant management, certain compensation costs, and general facility overhead charges.

	Real estate cost of sales includes depreciation, real estate taxes, insurance, repairs and maintenance and other costs directly associated with operating the Company’s portfolio of real property.

	Selling, General and Administrative Expenses – The Company includes non-production related costs from its alternative energy segment such as professional fees and certain payroll in selling, general and administrative expenses.

	The Company includes costs not directly related to operating its portfolio of real property from its real estate segment such as certain payroll and related costs, professional fees and other general expenses in selling, general and administrative expenses.

	Interest Cost – Interest expense of approximately $4,724,000 for fiscal year 2009 is net of $1,651,000 of interest capitalized related to equity investments and ethanol plant construction. No interest was capitalized during fiscal years 2011 and 2010. Cash paid for interest in fiscal years 2011, 2010 and 2009 was approximately $3,174,000, $4,701,000 and $2,886,000, respectively.

	Deferred Financing Costs – Direct expenses and fees associated with obtaining long-term debt are capitalized and amortized to interest expense over the life of the loan using the effective interest method.

	Financial Instruments – The Company uses derivative financial instruments to manage its balance of fixed and variable rate debt. The Company does not hold or issue derivative financial instruments for trading or speculative purposes. Interest rate swap agreements involve the exchange of fixed and variable rate interest payments and do not represent an actual exchange of the notional amounts between the parties. The swap agreements were not designated for hedge accounting pursuant to ASC 815. The interest rate swaps are recorded at their fair values and the changes in fair values are recorded as gain or loss on derivative financial instruments in the statements of consolidated operations. The Company paid settlements of interest rate swaps of approximately $2,436,000, $2,477,000 and $2,510,000 in fiscal years 2011, 2010 and 2009, respectively.

	Forward grain purchase and ethanol and distillers grains sale contracts are accounted for under the “normal purchases and normal sales” scope exemption of ASC 815, because these arrangements are for purchases of grain that will be delivered in quantities expected to be used and sales of ethanol quantities expected to be produced over a reasonable period of time in the normal course of business.

	Stock Compensation – The Company has stock-based compensation plans under which stock options have been granted to directors, officers and key employees at the market price on the date of the grant. The Company adopted ASC 718 “Compensation-Stock Compensation”, “(ASC 718”) on February 1, 2006. The Company chose the Modified Prospective Application (“MPA”) method for implementing this accounting standard. Under the MPA method, new awards, if any, are valued and accounted for prospectively upon adoption. Outstanding prior awards that were unvested as of February 1, 2006 are recognized as compensation cost over the remaining requisite service period. ASC 718 also required the Company to establish the beginning balance of the additional paid in capital pool (“APIC pool”) related to actual tax deductions from the exercise of stock options. This APIC pool is available to absorb tax shortfalls (actual tax deductions less than recognized compensation expense) recognized subsequent to the adoption of ASC 718. On November 10, 2005, the FASB issued FASB Staff Position No. FAS 123R-3, “Transition Election Related to Accounting for Tax Effects of Share-Based Payment Awards.” This FASB Staff Position provided companies with the option to use either the transition method prescribed by ASC 718 or a simplified alternative method described in the staff position. The Company chose to utilize the transition method prescribed by ASC 718, which requires the calculation of the APIC pool as if the Company had adopted ASC 718 for fiscal years beginning after December 15, 1994.

	No options were granted in the fiscal years ended January 31, 2012, January 31, 2011 or January 31, 2010. The following table summarizes options granted, exercised and canceled or expired during the fiscal year ended January 31, 2012:

	The total intrinsic value of options exercised in the fiscal years ended January 31, 2012, 2011 and 2010, was approximately $3.2 million, $0.7 million and $7.2 million, respectively, resulting in tax deductions to realize benefits of approximately $1.2 million, $0.3 million and $0.5 million, respectively. At January 31, 2012, there was no unrecognized compensation cost related to nonvested stock options. See Note 12 for a further discussion of stock options.

	Income Taxes – The Company provides for deferred tax liabilities and assets for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. The Company provides for a valuation allowance if, based on the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.

	Discontinued Operations – The Company classifies sold real estate assets and operations from its former retail segment in discontinued operations when the operations and cash flows of the store or real estate assets have been (or will be) eliminated from ongoing operations and when the Company will not have any significant continuing involvement in the operation of the store or real estate assets after disposal. To determine if cash flows had been or would be eliminated from ongoing operations, the Company evaluates a number of qualitative and quantitative factors. For purposes of reporting the operations of stores or real estate assets meeting the criteria for discontinued operations, the Company reports net sales and revenue, gross profit and related selling, general and administrative expenses that are specifically identifiable to those stores operations or real estate assets as discontinued operations. For stores and warehouses closed for which the Company has a retained interest in the related real estate, operations are presented in the real estate segment. Certain corporate level charges, such as general office expense, certain interest expense, and other “fixed” expenses are not allocated to discontinued operations because the Company believes that these expenses were not specific to components’ operations.

	New Accounting Pronouncements – Effective February 1, 2012, the Company will be required to adopt the third phase of amended guidance in ASC 820, which achieves common fair value measurement and disclosure requirements by improving comparability of fair value measurements presented and disclosed in financial statements prepared in accordance with GAAP and those prepared in conformity with International Financial Reporting Standards (“IFRS”). The Company has not determined the impact this amended guidance will have on its consolidated financial statements.

	Effective February 1, 2012, the Company will be required to adopt the amended guidance in ASC Topic 220, “Comprehensive Income”, which increases the prominence of other comprehensive income in the financial statements. The Company has not determined the impact this amended guidance will have on its consolidated financial statements.

	Effective February 1, 2011, the Company adopted the amended guidance is ASC 805, which requires disclosure of pro forma revenue and earnings as if the business combination that occurred during the reporting period had occurred as of the beginning of the comparable prior reporting year. The adoption of this amended guidance required expanded disclosure in the consolidated financial statements but did not impact financial results.

	Effective February 1, 2011, the Company adopted the second phase of the amended guidance in ASC 820, which requires the Company to disclose information in the reconciliation of recurring Level 3 measurements about purchases, sales, issuances and settlements on a gross basis, separately for assets and liabilities. The adoption of this amended guidance required expanded disclosure in the consolidated financial statements but did not impact financial results.

2.	INVESTMENTS AND DEPOSITS

	The Company has $743,000 at January 31, 2012 and 2011 on deposit with the Florida Department of Financial Services to secure its obligation to fulfill future obligations related to extended warranty contracts sold in the state of Florida.

	In addition to the deposit with the Florida Department of Financial Services, the Company has $620,000 and $857,000 at January 31, 2012 and 2011, respectively, invested in a money market mutual fund to satisfy Florida Department of Financial Services regulations.

	The Company’s equity investments are accounted for under ASC 323 “Investments-Equity Method and Joint Ventures”. The following table summarizes equity method investments at January 31, 2012 and 2011 (amounts in thousands):


Entity	Ownership Percentage			Carrying Amount January 31, 2012		Carrying Amount January 31, 2011

Big River Resources, LLC		10	%	$	34,370	$	29,443
Patriot Renewable Fuels, LLC		26	%		27,309		21,829
NuGen Energy, LLC (1)		48	%		—		16,077


Total Equity Method Securities				$	61,679	$	67,349


	(1) Ownership percentage through November 1, 2011.

	During fiscal year 2007, the Company entered into an agreement to invest $20 million in Big River, an Iowa limited liability company and holding company for several entities. The Company funded this investment in exchange for a 10% ownership interest. Big River Resources West Burlington, LLC, a wholly owned subsidiary of Big River, presently operates an ethanol manufacturing plant with an annual nameplate capacity of 92 million gallons. Big River Resources Galva, LLC, a wholly owned subsidiary of Big River, presently operates an ethanol manufacturing plant with an annual nameplate capacity of 100 million gallons. Big River Resources United Energy, LLC, a 50.5% owned subsidiary of Big River, operates an ethanol manufacturing plant with an annual nameplate capacity of 100 million gallons. Big River Resources Boyceville, LLC, a wholly owned subsidiary of Big River, presently operates an ethanol manufacturing plant with an annual nameplate capacity of 55 million gallons. The Company recorded income of approximately $6,931,000, $5,387,000 and $2,487,000 as its share of earnings from Big River during fiscal years 2011, 2010 and 2009, respectively. At January 31, 2012, the carrying value of the investment in Big River is approximately $34.4 million; the amount of underlying equity in the net assets of Big River is approximately $32.8 million. The excess of the carrying value of the investment over the underlying equity in the net assets is accounted for as goodwill and is recorded within equity method investments on the accompanying Consolidated Balance Sheets.

	During fiscal year 2007, the Company entered into an agreement to invest $16 million in Patriot. The Company funded this investment in exchange for a 23% ownership interest. During fiscal year 2011, the Company invested an additional $1.9 million which increased its ownership interest (effective January 1, 2012) in Patriot to 26%. The facility has an annual nameplate capacity of 100 million gallons and began operations during the second quarter of fiscal year 2008. The Company recorded income of approximately $5,274,000, $5,159,000 and $3,540,000 as its share of earnings or loss from Patriot during fiscal years 2011, 2010 and 2009, respectively. At January 31, 2012, the carrying value of the investment in Patriot is approximately $27.3 million; the amount of underlying equity in the net assets of Patriot is approximately $22.2 million. The excess of the carrying value of the investment over the underlying equity in the net assets is accounted for as goodwill and capitalized interest and is recorded within equity method investments on the accompanying Consolidated Balance Sheets. Capitalized interest is amortized as a basis difference over the life of the asset.

	Effective July 1, 2010, the Company purchased a 48% equity interest in NuGen which operates an ethanol producing facility in Marion, South Dakota with an annual nameplate capacity of 100 million gallons. The Company’s investment included approximately $2,410,000 paid at closing to the then sole shareholder of NuGen and $6,805,000 contributed directly to NuGen. An additional $6,451,000 was due based upon cash distributions from NuGen that REX was entitled to until such balance was paid (“Contingent Consideration”). The Company determined that the fair value of the Contingent Consideration, at the acquisition date, was approximately $4,611,000. On November 1, 2011, the Company acquired an additional 50% equity interest in NuGen. Following the purchase, the Company owns all of the outstanding Class A membership interest units in NuGen, representing a 100% voting interest and a 98% equity interest in NuGen. The Company recorded income (under the equity method of accounting) of approximately $9,327,000 and $4,011,000 as its share of earnings from NuGen during fiscal years 2011 and 2010. Effective November 1, 2011, the Company ceased using the equity method of accounting and began consolidating the results of NuGen. Prior to fiscal year 2011, the Company recorded the results of NuGen on a one month lag. During fiscal year 2011, NuGen adopted the same fiscal year as the Company. As a result, the Company no longer records the results of NuGen on a one month lag. The impact of recording 13 months (ten months of equity method income and three months of consolidated operations) of NuGen’s results in fiscal year 2011 was not material, representing an increase to net income of approximately $0.9 million.

	On September 30, 2006, the Company acquired 47% of the outstanding membership units of Levelland Hockley County Ethanol, LLC, or Levelland Hockley, for $11.5 million. On December 29, 2006, the Company purchased a $5.0 million convertible secured promissory note from Levelland Hockley. On July 1, 2007, the Company converted the note into equity and increased its ownership percentage to approximately 56%.

	Levelland Hockley, which is located in Levelland, Texas, commenced production operations in the first quarter of fiscal year 2008. The plant has an annual nameplate capacity of 40 million gallons of ethanol and 135,000 tons of dried distillers grains.

	The plant was shut down in early January 2011 as a result of industry wide low crush spread margins and the plant’s inability to source grain at affordable prices. On January 31, 2011, the Company sold 814,000 of its membership units to Levelland Hockley for $1, reducing the ownership interest in Levelland Hockley to 49%. As a result, the Company no longer has a controlling financial interest in Levelland Hockley, and, therefore, effective January 31, 2011, the Company deconsolidated Levelland Hockley and began using the equity method of accounting. In connection with the deconsolidation, the Company recorded its remaining noncontrolling equity interest and debt investments at fair value. The Company’s estimate of fair value for all of its investments in Levelland Hockley was $0 at January 31, 2011. The Company recorded a pretax charge of approximately $18.4 million as a result of deconsolidating Levelland Hockley and writing its remaining investments in Levelland Hockley to $0 at January 31, 2011. The deconsolidation loss was computed as the difference between the sales proceeds and fair value of the retained investment and the Company’s carrying value of the investment prior to the transaction. The Company’s continuing involvement as an equity method investor precludes classification of this transaction as discontinued operations. The Company also recorded a pretax loss from the operating results of Levelland Hockley (prior to deconsolidation) of approximately $5.9 million. On April 27, 2011, Levelland Hockley voluntarily filed for protection under Chapter 11 of the United States Bankruptcy Code in the United States Bankruptcy Court, Northern District of Texas. As a result, the Company no longer could exercise significant influence over Levelland Hockley and began using the cost method of accounting. There was no change in the carrying value of the Company’s investments in Levelland Hockley as a result of the change to the cost method of accounting.

	Undistributed earnings of equity method investees totaled approximately $22.8 million and $18.4 million at January 31, 2012 and 2011, respectively.

	Summarized financial information for each of the Company’s equity method investees, as of their fiscal year end is presented in the following table (amounts in thousands):

Business Combination Disclosure [Text Block]


3.	BUSINESS COMBINATIONS

	On November 1, 2011, the Company acquired an additional 50% of the outstanding membership units of NuGen. This acquisition resulted in the Company owning approximately 98% of the outstanding membership units in NuGen and also resulted in the Company obtaining a controlling financial interest in NuGen. This has been accounted for as a business combination achieved in stages. NuGen operates an ethanol production facility in Marion, South Dakota that has an annual nameplate capacity of 100 million gallons of ethanol.

	The results of NuGen’s operations have been included in the consolidated financial statements subsequent to the acquisition date and are included in the Company’s alternative energy segment. Subsequent to the acquisition date, the Company has included approximately $84.1 million of net sales and revenue and approximately $4.0 million of net income from NuGen in its Consolidated Statement of Operations for fiscal year 2011. The Company paid approximately $10.4 million of cash and the fair value of the Company’s previously held equity interest in NuGen was approximately $18.6 million.

	The acquisition was recorded by allocating the total purchase price to the assets acquired, including intangible assets and liabilities assumed, based on their estimated fair values at the acquisition date. The following table summarizes the estimated fair values of the assets acquired and liabilities assumed at the date of acquisition (amounts in thousands):


Cash	$	24,971
Accounts receivable		7,381
Inventory		8,491
Prepaid expenses and other current assets		711
Property, plant and equipment		78,618
Other		2,995

Total assets acquired		123,167
Current liabilities		(19,167	)
Long term debt		(65,000	)
Noncontrolling interest		(955	)
Gain on acquisition		(8,990	)

Cash paid	$	10,413

Fair value of 48% equity method investment	$	18,642


	Prior to this acquisition, the Company owned 48% of NuGen. In accordance with ASC 805, the Company accounted for this transaction as a step acquisition, remeasured its previously held investment to fair value and recorded the approximately $5.4 million difference between fair value and its carrying value as equity method remeasurement loss. The acquisition date fair value of the Company’s 48% interest in NuGen was approximately $18.6 million, and the carrying value was approximately $24.0 million. This fair value was determined using a market and income approach, both of which contain significant unobservable inputs.

	ASC 805 requires that when the fair value of the net assets acquired exceeds the purchase price, resulting in a bargain purchase gain, the acquirer must reassess the reasonableness of the values assigned to all of the net assets acquired, liabilities assumed and consideration transferred. The Company has performed such a reassessment and has concluded that the values assigned to the NuGen acquisition are reasonable. The net assets acquired less liabilities assumed exceeded the purchase price by approximately $8.9 million which was recorded as bargain purchase gain. The fair value of the net assets acquired was determined using a market and income approach, both of which contain significant unobservable inputs.

	The bargain purchase gain of approximately $8.9 million, combined with the loss related to the equity method remeasurement of approximately $5.4 million is recorded as “Bargain Purchase Gain, Net” on the accompanying Consolidated Statement of Operations.

	The Company believes this transaction resulted in a bargain purchase because the previous owners of NuGen acquired the plant out of bankruptcy during fiscal year 2009 at a relatively low purchase price. Therefore, the purchase price the Company paid for NuGen provided an adequate rate of return to the previous owners. In addition, the preexisting relationship the Company had with the previous owners, by way of its initial 48% equity method investment and option to purchase up to 51% of NuGen, limited the ability of the previous owners to market the plant for sale.

	The unaudited financial information in the table below summarizes the combined results of operations of the Company and NuGen, on a pro forma basis, as though the companies had been combined as of the beginning of fiscal year 2010 (in thousands, except per share amounts):


	Year Ended January 31, 2012		Year Ended January 31, 2011

Net sales and revenue	$	684,615	$	561,748
Net income	$	34,939	$	9,271
Basic net income per share	$	3.83	$	0.96
Diluted net income per share	$	3.80	$	0.94


	Transaction costs related to the acquisition of NuGen were insignificant.

FAIR VALUE

Jan. 31, 2012

Fair Value Disclosures [Text Block]


4.	FAIR VALUE

	The Company applies ASC 820, which defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

	The Company determines the fair market values of its financial instruments based on the fair value hierarchy established by ASC 820, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair values which are provided below. The Company carries certain cash equivalents, restricted and other investments and derivative liabilities at fair value.

	Level 1 – Quoted prices in active markets for identical assets or liabilities. Level 1 assets and liabilities include debt and equity securities and derivative contracts that are traded in an active exchange market, as well as certain U.S. Treasury securities that are highly liquid and are actively traded in over-the-counter markets.

	Level 2 – Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 2 assets and liabilities include derivative contracts whose value is determined using a pricing model with inputs that are observable in the market or can be derived principally or corroborated by observable market data.

	Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methods, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation. Unobservable inputs shall be developed based on the best information available, which may include the Company’s own data.

	The fair values of derivative assets and liabilities traded in the over-the-counter market are determined using quantitative models that require the use of multiple market inputs including interest rates, prices and indices to generate pricing and volatility factors, which are used to value the position. The predominance of market inputs are actively quoted and can be validated through external sources, including brokers, market transactions and third-party pricing services. Estimation risk is greater for derivative asset and liability positions that are either option-based or have longer maturity dates where observable market inputs are less readily available or are unobservable, in which case interest rate, price or index scenarios are extrapolated in order to determine the fair value. The fair values of derivative assets and liabilities include adjustments for market liquidity, counterparty credit quality, the Company’s own credit standing and other specific factors, where appropriate. The fair values of property and equipment are determined by using various models that discount future expected cash flows. Estimation risk is greater for vacant properties as the probability of expected cash flows from the use of vacant properties is difficult to predict.

	To ensure the prudent application of estimates and management judgment in determining the fair value of derivative assets and liabilities and property and equipment, various processes and controls have been adopted, which include: model validation that requires a review and approval for pricing, financial statement fair value determination and risk quantification; periodic review and substantiation of profit and loss reporting for all derivative instruments. Financial assets and liabilities measured at fair value at January 31, 2012 on a recurring basis are summarized below (amounts in thousands):


	Level 1		Level 2		Level 3		Total Fair Value


Cash Equivalents	$	2	$	—	$	—	$	2
Money Market Mutual Fund (1)		620		—		—		620
Investment in Cooperative (1)		—		—		219		219

Total Assets	$	622	$	—	$	219	$	841


Interest Rate Swap Derivative Liabilities	$	—	$	4,235	$	—	$	4,235


	Financial assets and liabilities measured at fair value at January 31, 2011 on a recurring basis are summarized below (amounts in thousands):


	Level 1		Level 2		Level 3		Total Fair Value


Cash Equivalents	$	2	$	—	$	—	$	2
Money Market Mutual Fund (1)		857		—		—		857

Total Assets	$	859	$	—	$	—	$	859


Interest Rate Swap Derivative Liabilities	$	—	$	5,523	$	—	$	5,523


	(1) The money market mutual fund is included in “Restricted investments and deposits” and the investment in cooperative is included in “Other assets” on the accompanying Consolidated Balance Sheets.

	The following table provides a reconciliation of the activity related to assets measured at fair value on a recurring basis using Level 3 inputs (amounts in thousands):


	Investment in Cooperative


Balance, January 31, 2011	$	—
Equity allocation		218,777

Balance, January 31, 2012	$	218,777


	The Company determined the fair value of the investment in cooperative by using a discounted cash flow analysis on the expected cash flows. Inputs used in the analysis include the face value of the allocated equity amount, the projected term for repayment based upon a historical trend, and a risk adjusted discount rate based on the expected compensation participants would demand because of the uncertainty of the future cash flows. The inherent risk and uncertainty associated with unobservable inputs could have a significant effect on the actual fair value of the investment.

	No financial instruments were elected to be measured at fair value in accordance with ASC 470-20-25-21.

	The Company reviews its long-lived assets for impairment on at least an annual basis based on the carrying value of these assets. As a result of vacancies at owned real estate locations, the Company tested certain long-lived assets for impairment using a fair value measurement approach. The fair value measurement approach utilizes a number of significant unobservable inputs or Level 3 assumptions. These assumptions include, among others, the implied fair value of these assets using an income approach by preparing a discounted cash flow analysis and the implied fair value of these assets using recent sales data of comparable properties, and other subjective assumptions. Upon completion of its impairment analysis, which was performed at various times throughout fiscal year 2011, the Company determined that the carrying value of certain long-lived assets exceeded the fair value of these assets. Accordingly, the Company recorded long-lived asset impairment charges of approximately $1,227,000 to properly reflect the carrying value of these assets.

	Assets measured at fair value at January 31, 2012 on a non-recurring basis are summarized below (amounts in thousands):


	Year Ended January 31, 2012		Level 1		Level 2		Level 3		Total Losses


Property and equipment, net	$	8,803	$	—	$	—	$	8,803	$	1,227


	Assets measured at fair value at January 31, 2011 on a non-recurring basis are summarized below (amounts in thousands):


	Year Ended January 31, 2011		Level 1		Level 2		Level 3		Total Losses


Property and equipment, net	$	2,981	$	—	$	—	$	2,981	$	165

Notes receivable from Levelland Hockley	$	—	$	—	$	—	$	—	$	8,937


	Excluded from the table is information for losses on property and equipment, net that were classified as discontinued operations. Such losses totaled $856,000 in fiscal year 2010.

Earnings Per Share [Text Block]


7.	NET INCOME PER SHARE FROM CONTINUING OPERATIONS

	The Company reports net income per share in accordance with ASC 260, “Earnings per Share”. Basic net income per share is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the year. Diluted net income per share is computed by dividing net income available to common shareholders by the weighted average number of shares outstanding and dilutive common share equivalents during the year. Common share equivalents for each year include the number of shares issuable upon the exercise of outstanding options, less the shares that could be purchased under the treasury stock method. The following table reconciles the basic and diluted net income per share from continuing operations computations for each year presented for fiscal years 2011, 2010 and 2009 (amounts in thousands, except per-share amounts):


	2011


	Income		Shares		Per Share


Basic net income per share from continuing operations attributable to REX common shareholders	$	26,495		9,117	$	2.90
Effect of stock options				70

Diluted net income per share from continuing operations attributable to REX common shareholders	$	26,495		9,187	$	2.88

Long-term Debt [Text Block]


10.	LONG-TERM DEBT AND INTEREST RATE SWAPS

	Long-term debt consists of notes payable secured by certain land, buildings and equipment. Interest rates ranged from 3.2% to 8.4% in fiscal years 2011 and 2010. Principal and interest are payable periodically over terms that generally range up to 5 years. The following provides information on rates segregated as fixed or variable and by term for fiscal years 2011 and 2010:


	January 31, 2012

Interest Rates	Maturity		Balance (in thousands)

2015		52,696
2016		5,753
2017		32,998

	$	123,749


	The fair value of the Company’s long-term debt at January 31, 2012 and 2011 was approximately $123.8 million and $81.2 million, respectively. The fair value was estimated using a discounted cash flow analysis and the Company’s estimate of market rates of interest for similar loan agreements.

	One Earth Energy Subsidiary Level Debt

	During the third quarter of fiscal year 2009, pursuant to the terms of the loan agreement, One Earth converted their construction loan into a term loan. Beginning with the first quarterly payment on October 8, 2009, payments are due in 19 quarterly payments of principal plus accrued interest with the principal portion calculated based on a 120 month amortization schedule. One final installment will be required on the maturity date (July 31, 2014) for the remaining unpaid principal balance with accrued interest. The term loan bears interest at rates ranging from LIBOR plus 300 basis points to LIBOR plus 310 basis points (3.2% to 3.4% at January 31, 2012). Borrowings are secured by all property of One Earth. This debt is recourse only to One Earth and not to REX American Resources Corporation or any of its other subsidiaries. As of January 31, 2012, approximately $69.1 million was outstanding on the term loan. One Earth is also subject to certain financial covenants under the loan agreement, including required levels of EBITDA, working capital, debt service coverage ratio requirements and net worth requirements. One Earth was in compliance with these covenants at January 31, 2012.

One Earth has a $10.0 million revolving loan facility that matures May 31, 2012. Borrowings under this facility bear interest at LIBOR plus 280 basis points. One Earth has no outstanding borrowings on the revolving loan as of January 31, 2012.

One Earth also has access to a secondary revolving loan with First National Bank of Omaha, established as part of the original $100,000,000 term loan and made accessible as a revolving loan as term loan payments were made. The amount available is reduced by $250,000 on a quarterly basis as well as by 20% of excess cash flow calculated at year end pursuant to the covenant calculations of the loan agreement. At January 31, 2012 and 2011, One Earth had $2,671,000 and $5,384,000, respectively, on the secondary revolving loan available. One Earth did not have any outstanding borrowings on the secondary revolving loan at January 31, 2012 or 2011.

One Earth has paid approximately $1.4 million in financing costs. These costs are recorded as deferred financing costs and are being amortized ratably over the term of the loan. At January 31, 2012, the Company’s proportionate share of restricted assets related to One Earth was approximately $14.5 million. Such assets may not be paid in the form of dividends or advances to the parent company or other members of One Earth per the terms of the loan agreement with First National Bank of Omaha.

One Earth entered into two forward interest rate swaps in the notional amounts of $50.0 million and $25.0 million with the First National Bank of Omaha. The swap settlements commenced as of July 31, 2009; the $50.0 million swap terminates on July 8, 2014 and the $25.0 million swap terminated on July 31, 2011. The $50.0 million swap fixed a portion of the variable interest rate of the term loan subsequent to the plant completion date at 7.9% while the $25.0 million swap fixed the rate at 5.49%. At January 31, 2012 and 2011, One Earth recorded a liability of approximately $4.2 million and $5.5 million, respectively, related to the fair value of the swaps. The change in fair value is recorded in the Consolidated Statements of Operations.

NuGen Energy Subsidiary Level Debt

In November 2011, NuGen entered into a $65,000,000 financing agreement consisting of a term loan agreement for $55,000,000 and a $10,000,000 revolving loan with First National Bank of Omaha. The term loan bears interest at a variable interest rate of LIBOR plus 325 basis points, subject to a 4% floor. Beginning with the first quarterly payment on February 1, 2012, payments are due in 20 quarterly payments of principal plus accrued interest with the principal portion calculated based on a 120 month amortization schedule. One final installment will be required on the maturity date (October 31, 2016) for the remaining unpaid principal balance with accrued interest. This debt is recourse only to NuGen and not to REX American Resources Corporation or any of its other subsidiaries.

Borrowings are secured by all property of NuGen. As of January 31, 2012, approximately $53.6 million was outstanding on the term loan. NuGen is also subject to certain financial covenants under the loan agreement, including required levels of EBITDA and working capital and debt service coverage ratio requirements. NuGen was in compliance with these covenants, as applicable, at January 31, 2012. NuGen paid approximately $0.6 million in costs related to obtaining its financing arrangement. These costs are recorded as prepaid loan fees and are being amortized over the loan term. At January 31, 2012, the Company’s proportionate share of restricted assets related to NuGen was approximately $3.6 million. Such assets may not be paid in the form of dividends or advances to the parent company or other members of NuGen per the terms of the loan agreement with First National Bank of Omaha.


	NuGen has no outstanding borrowings on the $10,000,000 revolving loan as of January 31, 2012.

	On a consolidated basis, approximately 24.7% of the Company’s net assets (including equity method investees) are restricted as of January 31, 2012. Including only consolidated subsidiaries, approximately 7.1% of the Company’s net assets are restricted as of January 31, 2012.

As of January 31, 2012, the notional value of the interest rate swap was approximately $41.8 million. At January 31, 2012, the Company has recorded a liability of approximately $4.2 million related to the fair value of the swap.

14.	COMMITMENTS

	One Earth and NuGen have combined forward purchase contracts for approximately 10.3 million bushels of corn, the principal raw material for their ethanol plants. They expect to take delivery of the corn by July 2012.

	One Earth and NuGen have combined sales commitments for approximately 40.4 million gallons of ethanol and 59,300 tons of distillers grains. They expect to deliver the ethanol and the distillers grains by April 2012.

	Forward grain purchase, ethanol and distillers grains sale contracts are accounted for under the “normal purchases and normal sales” scope exemption of the accounting standards because these arrangements are for purchases of grain and sales of ethanol and distillers grains that will be delivered in quantities expected to be used by One Earth and NuGen over a reasonable period of time in the normal course of business.

	One Earth has entered into an agreement with an unrelated party for the use of a portion of the party’s natural gas pipeline. The term of the agreement is 10 years, and the amount is $4,380,000, which is spread over 120 equal payments of $36,500. Payments began in February 2009. One Earth paid approximately $438,000, $438,000 and $402,000 pursuant to the lease in fiscal years 2011, 2010 and 2009, respectively.

	One Earth has entered into an agreement with an unrelated party for the lease of railcars that will be used to ship ethanol. The lease expires on May 31, 2012, with an automatic 36-month extension, unless either party notifies the other in writing 60 days prior to the initial expiration date. One Earth pays a monthly lease amount per railcar. One Earth paid approximately $744,000, $660,000 and $344,000 pursuant to the lease in fiscal years 2011, 2010 and 2009, respectively.

	One Earth has entered into an agreement with an unrelated party for the lease of railcars that will be used to ship ethanol. The lease expires on June 30, 2012, and shall continue under lease for successive one month terms, unless notified in writing 30 days prior to the initial expiration date or any successive term. One Earth pays a monthly lease amount per railcar. One Earth paid approximately $449,000, $662,000 and $69,000 pursuant to the lease in fiscal years 2011, 2010 and 2009, respectively.

	One Earth has a contract with an unrelated party (“Distillers Grains Marketer”) for distillers grains marketing services. Under the terms of the contract, the Distillers Grains Marketer will purchase all of One Earth’s distillers grains production during the term of the contract. The contract called for One Earth to pay a fee per ton of distillers grains for the Distillers Grains Marketer’s services. The contract was amended on December 6, 2010, to reduce the fee for DDGS, and the termination date was extended to July 1, 2014. One Earth paid approximately $627,000 and $905,000 in fiscal years 2011 and 2010, respectively, for these marketing services.

	One Earth has a grain origination agreement with Alliance Grain, under which it purchased 100% of its grain during fiscal years 2011, 2010 and 2009. One Earth pays to Alliance Grain a certain amount per bushel for procurement fees. The term of the agreement expires Oct. 31, 2014, and shall renew automatically for additional one year terms, unless either party sends notice to the other party of its intent to terminate the agreement at least 180 days prior to the expiration of the then current term of the agreement.

	NuGen entered into an agreement with unrelated parties for the lease of railcars that will be used to ship ethanol and distillers grains. These leases expire during fiscal year 2012. NuGen paid approximately $482,000 in fiscal year 2011 for the rail car leases.

	The Company has approximately $24.0 million and $23.4 million of AMT credit carryforwards as of January 31, 2012 and 2011, respectively. The AMT credit carryforwards can be used to offset future regular income tax liabilities subject to certain limitations. The AMT credit carryforwards have no expiration date. The Company must generate approximately $160 million in future taxable income to fully utilize the AMT credit carryforward. If the Company is not able to generate sufficient taxable income in subsequent years to allow for the utilization of the deferred tax assets, the Company would need to provide a valuation allowance for such deferred tax assets, thus increasing income tax expense.

	The Company has state net operating loss carryforwards of approximately $31.5 million, net of the federal benefit, which will begin to expire in fiscal year 2012.

	The Company has a valuation allowance of approximately $1,676,000 at January 31, 2012. The Company increased the valuation allowance by $434,000 and $664,000 in fiscal years 2011 and 2010, respectively. These adjustments to the valuation allowance are a result of estimates of realizing certain future state tax benefits. No adjustment was made in fiscal year 2009.

	The Company paid income taxes of $1,550,000, $1,310,000 and $14,000 in fiscal years 2011, 2010 and 2009, respectively. The Company received refunds of income taxes of $7,208,000, $5,691,000 and $1,105,000 in fiscal years 2011, 2010 and 2009, respectively.

	The effective income tax rate on consolidated pre-tax loss or income differs from the federal income tax statutory rate for fiscal years 2011, 2010 and 2009 as follows:


	2011			2010			2009


Federal income tax at statutory rate		35.0	%		35.0	%		35.0	%
State and local taxes, net of federal tax benefit		4.1			4.1			3.9
Net increase in valuation allowance		1.0			9.8			—
Domestic production activities deduction		(3.2	)		—			—
Uncertain tax positions		0.2			1.5			(0.3	)
Noncontrolling interest		(4.1	)		(17.7	)		(8.0	)
Other		0.3			(2.8	)		0.5


Total		33.3	%		29.9	%		31.1	%


	The Company files a U.S. federal income tax return and income tax returns in various states. In general, the Company is no longer subject to U.S. federal, state or local income tax examinations by tax authorities for fiscal years ended January 31, 2005 and prior.

	The Company applies the provisions of ASC 740-10-25-5 for uncertain tax positions. As a result of the adoption of this accounting standard, the Company recorded a $287,000 decrease to retained earnings. As of January 31, 2012, total unrecognized tax benefits were $2,157,000, and accrued penalties and interest were $327,000. If the Company were to prevail on all unrecognized tax benefits recorded, approximately $82,000 of the reserve would benefit the effective tax rate. In addition, the impact of penalties and interest would also benefit the effective tax rate. Interest and penalties associated with unrecognized tax benefits are recorded within income tax expense.

	On a quarterly and annual basis, the Company accrues for the effects of open uncertain tax positions and the related potential penalties and interest. It is reasonably possible that the amount of the unrecognized tax benefit with respect to certain unrecognized tax positions will increase or decrease during the next 12 months; however, the Company does not expect the change to have a material effect on results of operations or financial position. A reconciliation of the beginning and ending amount of unrecognized tax benefits, including interest and penalties, is as follows (dollars in thousands):


	Years Ended January 31,

	2012			2011


Unrecognized tax benefits, beginning of year	$	2,976		$	2,338
Changes for tax positions for prior years		(492	)		104
Changes for tax positions for current year		—			534


Unrecognized tax benefits, end of year	$	2,484		$	2,976

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

CONTINGENCIES

Contingencies Disclosure [Text Block]


18.	CONTINGENCIES

	The Company sold its entire interest, through a series of transactions, in three former partnerships (Colona, Somerset and Gillette) that owned synthetic fuel facilities. As such, the Company was no longer allocated Section 29/45K tax credits after fiscal year 2005. In connection with the Colona and Somerset sales, the Company received contingent payments based upon percentages of qualified Section 29/45K credits generated. In connection with the sale of the Gillette partnership, the Company was eligible to receive contingent payments based upon the amount of “qualified production.” The Company has recognized approximately $7.7 million of income from these sales from years the partnerships have open tax years with the IRS. In the event that the synthetic fuel tax credits are reduced as a result of IRS audits, the amount of proceeds realized from the sales could be significantly impacted.

	The Company is involved in various legal actions arising in the normal course of business. After taking into consideration legal counsels’ evaluation of such actions, management is of the opinion that their outcome will not have a material effect on the Company’s consolidated financial statements.

- Definition

The entire disclosure for loss and gain contingencies. Describes any existing condition, situation, or set of circumstances involving uncertainty as of the balance sheet date (or prior to issuance of the financial statements) as to a probable or reasonably possible loss incurred by an entity that will ultimately be resolved when one or more future events occur or fail to occur, and typically discloses the amount of loss recorded or a range of possible loss, or an assertion that no reasonable estimate can be made.

Segment Reporting Disclosure [Text Block]


19.	SEGMENT REPORTING

	Beginning in the second quarter of fiscal year 2009, the Company realigned its reportable business segments to be consistent with changes to its management structure and reporting. The Company has two segments: alternative energy and real estate. In prior years, the real estate segment was formerly included in the retail segment and historical amounts have been reclassified to conform to the current year segment reporting presentation. For stores and warehouses closed for which the Company has a retained interest in the related real estate, operations are presented in the real estate segment when retail operations cease. The Company evaluates the performance of each reportable segment based on segment profit. Segment profit excludes income taxes, indirect interest expense, discontinued operations, indirect interest income and certain other items that are included in net income determined in accordance with accounting principles generally accepted in the United States of America. Amounts below include corporate activities that are not separately reportable and income from synthetic fuel investments (amounts in thousands):

	Additions to other long lived assets represent primarily equity method investments and long term refundable real estate taxes.

	Certain corporate costs and expenses, including information technology, employee benefits, and other shared services, are allocated to the business segments. The allocations are generally amounts agreed upon by management, which may differ from amounts that would be incurred if such services were purchased separately by the business segment. Corporate assets are primarily cash and equivalents, deferred income tax benefits and refundable income taxes.

	Cash, except for cash held by One Earth and NuGen, is considered to be fungible and available for both corporate and segment use depending on liquidity requirements. Cash of approximately $28.9 million held by One Earth and NuGen will be used primarily to fund working capital needs for the subsidiaries.

- Definition

The entire disclosure for reporting segments including data and tables. Reportable segments include those that meet any of the following quantitative thresholds a) it's reported revenue, including sales to external customers and intersegment sales or transfers is 10 percent or more of the combined revenue, internal and external, of all operating segments b) the absolute amount of its reported profit or loss is 10 percent or more of the greater, in absolute amount of 1) the combined reported profit of all operating segments that did not report a loss or 2) the combined reported loss of all operating segments that did report a loss c) its assets are 10 percent or more of the combined assets of all operating segments.
